Actually, the eBooks Feedbooks formats are very poor. Bad things are being done under the hood.

.chapterHeader .translation {
  float:left;
  font-weight: normal;
  margin-top:38px;
  margin-left: -8px;
  margin-bottom: 0px;
  padding-right: 16px;
  padding-left: 5px ;
  padding-bottom: 0px;
  padding-top: 0px;
  font-size:26px;
  background-color:#FFF;}
                             
.chapterHeader .count {
  line-height: 100%;
  font-style:normal;
  font-weight: normal;
  text-transform:uppercase;
  font-size:94px;
  margin-right:18px;
  margin-top:-14px;
  margin-bottom: -20px;
  float:left;
  padding:0px;
  background-color:#FFF;}

Using px as a measurement is very bad form. We've already seen that Kobo ignores px. But these eBooks should not be using px anyway. Just changing px to em would not work well as that would change some things to be way too large. Feedbooks needs to figure out the closest em equivalent and fix things so they work.

So you'll need to pick a better created eBook to show off as the ones from Feebooks do not count since they break the rules in a very bad way.
